objective: this study was conducted to identify the characteristics of patients with psychosis who had escaped from hospital or were discharged prematurely and against medical advice. method: we carried out this retrospective study on 72 patients with psychosis who were discharged prematurely over a 38-month period and compared them to 76 patients with psychosis who were discharged according to...

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...

background: the main cause of discontinuing the use of depomedroxy progesterone acetate (dmpa) is irregular bleeding. this study compared placebo with two kinds of combined oral contraceptive pills including low dose (ldocp) and high dose (hdocp) on control of abnormal uterine bleeding in dmpa users. methods: ninety dmpa users complaining of bleeding were studied in a triple blind randomized cl...

a novel discrete singular convolution (dsc)  formulation  is  presented for the seepage analysis in irregular geometric porous media. the dsc is a new promising numerical approach which has been recently applied to solve several engineering problems. for a medium with regular geometry, realizing of the dsc for the seepage analysis is straight forward. but dsc implementation for a medium with ir...

A lot of techniques have been developed for the encoding of triangular meshes as this is a widely used representation for the description of surface models. Although methods for the encoding of the neighbor information, the connectivity, are near optimal, there is still room for better encodings of vertex locations, the geometry. Our geometry encoding strategy follows the predictive coding para...

Two families of conforming finite elements for the two-dimensional Stokes problem are developed, guided by two discrete smoothed de Rham complexes, which we coin “Stokes complexes.” We show that the finite element pairs are inf-sup stable and also provide pointwise mass conservation on very general triangular meshes.

We investigate how to create an integrated and consistent model of terrain and network data, and define a geometric simplification method that uses an underlying triangulated irregular network (TIN) representation to maintain the topological relationships of the embedded network. The method is used to create a consistent multiresolution data structure. An edge collapse strategy is described tha...

We study the simplification of triangular and tetrahedral meshes using techniques based on successive edge collapses, as well as the exploitation of the generated multiple levels of detail for the effective processing of the models. Regarding triangular meshes, we present a method for the construction of progressive hulls, by suitable edge collapses; we use the generated hulls for the accelerat...

In this paper we shall introduce a simple, effective numerical method to compute differential operators for scalar and vector-valued functions on regular surfaces. The key idea of our algorithm is to develop an intrinsic and unified way to compute directly partial derivatives of functions defined on triangular meshes which are the discretizations of regular surfaces under consideration. Most im...
